Interpersonal Massager Pt 01

**Authors Note: This was my first attempt at writing a story. It was written by me on a choose-your-own-adventure site.

Description: A guy in a failing relationship re-engineers a personal massager project from work and finds it surprisingly useful for brainwashing the women in his life.**

-Chapter 1-

I enjoyed my job. I really did; unfortunately, very few of the customers at my maker space used me as a resource for projects.

People came in with really good ideas every day, but very few of those ideas turned into usable products. My job was to help these people's ideas turn into finished products. I taught classes on how to use the machine shop, woodworking tools, 3D printers, and computer design software. I also was available to give engineering and design advice, but it was very rare for others to accept my help.

Constructive criticism wasn't usually taken well for whatever reason. Most customers would rather vainly continue with a flawed design rather than accept some advice from a professional engineer and inventor. Maybe it was because I was the same age as most of my customers at 25, I don't know.

Either way, work had become a welcome break from my home life. I had a beautiful petite red-headed girlfriend named Kelly. I truly loved her unconditionally after the 5 years we'd spent together. She was as smart, or even smarter than me, kind, fun, and loving in her own way. She was never as intimate, touchy, or expressive of her love as I was, but I accepted that; however, she had been getting more and more distant. The sex went from a couple of times a month, which was bad enough, to maybe a pity screw every couple of months. She became detached and disinterested in me quickly. I tried everything I could to re-spark our relationship, but nothing worked. She had already made up her mind, and there was no changing the mind of a girl like her.

I wasn't much to look at. Pretty below average overall. 5'-10" tall, lanky, and starting to bald and get grey hair at 25. On the other hand she was cute and petite at 5'-1" and finally filling out to be a curvy, sexy, woman, with the perkiest B cups I'd ever seen, and a small but definitely nice round backside compared to her tiny waist. My attraction to her still grew every day, but the same wasn't true in her eyes.

I knew she had fallen out of love, but she was just scared to move on after building a life with me. I couldn't bring myself to let her go either. I still thought I could fix things, and I knew she wasn't cheating on me yet.

I still had my work to look forward to at least. In the last couple of years, my little upstart had done pretty well. I got loads of grant money and donations. The city had wanted someone to start up a maker space for years, so they made sure I had enough funding. People either paid a small membership fee or got a one-day pass. I had enough business to cover nice salaries for myself and my only employee, Caitlin.

I didn't know much about Caitlin, except she was a Jack of all trades kind of like me. That's why I hired her despite not having any of the qualifications listed in my job advertisement. She was smart enough to figure out all the machinery on her own, or read the manuals when needed and she was a quick learner. The actual post-grad engineers (like myself) that applied didn't have a clue how to operate a lathe, much less how to teach a layman how to use one safely. Caitlin could.

I don't know much else about her. I think she's single. She moved a long way from home to work here and she mentioned to me once she didn't have a family she intended to see again. She's a redhead with a cute face, I can't tell much else because she's usually wearing the company coveralls. I wouldn't mind seeing more of her though...

Buzzzzzz!

I was knocked out of my daydream by a buzzing sound coming from one of the workbenches.

-Chapter 2-

A regular in the maker space named Mike had finally gotten his prototype personal massager working. It was actually a pretty neat idea. It was a 3D-printed ring that fit on two fingers. Pretty much anyone would assume it was a homemade vibrating cock ring, but it was actually a bit different. The inside of the ring contained several small vibrators, that also made contact with sheets of piezoelectric material. The outside of the ring had an electrical wire wrapped around it that transferred the tiny electrical shocks to wherever the user was massaging while the vibrators also stimulated the area. The part of the ring touching the finger was shielded with silicone to prevent shock and vibration fatigue on the user's hand.

Mike's design was crude and badly constructed. I had offered him several ideas along the way to make it work better, but he ignored them all and continued his initial design for months. I was honestly surprised he got it to work.

"Shit!" Mike exclaimed as the little machine started grinding and let out a puff of smoke. "You know what I'm done with this," he said looking towards me, "you can have it, Clayton." He angrily began walking out.

"Wait, Mike, you're really close let me help you 3D print a new casing for it. This can easily be saved." I yelled after him, but he just held out his hands and walked out.

I picked up the ruined device and put it in the drawer of my desk in case he had a change of heart. A few hours later though I got an email that he canceled his membership to the maker space.

Shaking my head, I replied to the email that I was sorry to see him go and wished him luck.

I pulled the ring back out and wondered if it would be unethical to re-engineer it for myself. "Kelly might enjoy it," I thought out loud.

-Chapter 3-

I decided to think more about it the next day. It was nearing the 8 pm closing time of my shop, so it was time to get everyone to clean up their workspaces and shut down all the machinery.

Around 9:30 pm I finally pulled into my driveway. My fingers were crossed that Kelly would be in a happy mood. I was always excited to see her, but it was rare for her to reciprocate that feeling.

She was sitting on the couch when I came wearing a pink tank top and covered up with a blanket. I kneeled down to give her a hug and a kiss "hi cutie, how has your day been," I asked. she turned her head just enough to show she didn't want a kiss. So I only hugged her.

"My day was good," she said as she squirmed out of my hug, "but Clay, we need to talk."

I knew what was coming, we had already had a talk the week before where she asked me for more space. I gave her her space by working 2 shifts a day the last seven days at work and only talking to her briefly to say hello and bye. I guess that wasn't enough. I felt the lump in my throat get a bit bigger.

"I've started looking at apartments," she said with stern emotionless eyes, "I think we both know this isn't working anymore... I wish it was different. I still care about you Clay, but I don't feel anything at all anymore, and you and I both deserve better."

We'd already had all the arguments, and I'd changed as much as I could for her. I knew this was really it this time. I sighed and sat down for a minute thinking.

"Kelly, I don't want to let you go, but I know this has been coming." I said, "just please let me know when you are going to leave. I don't want to be here to see... I don't want to watch you move out."

"I'll let you know. I should be able to start a lease 3 weeks from now if you can help me with a deposit. Otherwise, I can't leave for another month." She said.

Our conversation went on. I agreed to help her out in exchange for her leaving the washer and dryer we bought together. I already paid off the mortgage with the house in my name, so I could afford to live alone with a few changes to my budget. She was in for a rude awaking though and I truly did want her to be ok.

There were no tears from me. Things like this didn't hit me until much later. We went to bed separately.

-Chapter 4-

I had to get my mind off things. For the next few days, I redesigned the ring from scratch. I didn't really expect it to be anything special. The market is already swamped with massagers and vibrators, so this was just for fun.

I 3D printed a new ring that would fit perfectly on my index and middle fingers together just like Mike's design. I made several upgrades. I ordered a custom rechargeable battery that took up about half of the ring's interior. It was rechargeable through two small recessed pins on the inside of the ring which sat on a custom dock I created for it. I used the same piezo/vibrator layout, but I used a brass inlay to transfer the electric shocks to the target area instead of the bare wires Mike used.

It turned on the first try when I inserted my fingers into it. It hummed to life with a very musical... calming tone. I programmed the vibration to slowly vary in intensity and frequency using a randomly generated algorithm. I was lucky to generate one that worked well, but I had no idea just how lucky.

I started up a timer to measure battery time and gave it a test. I tested it on my arm first. Surprisingly, it felt really interesting. The shocks were subtle. They reminded me of a shock treatment I had in physical therapy one time. Coupled with the vibrations it was pretty nice. I moved it up to the back of my neck where it was sore from bad posture. It felt very calming there.

"Earth to Clayton!" Caitlin yelled and startled me.

"Oh hey Caitlin, sorry I was testing this massager out," I said surprised, "what can I do for you?"

"It apparently works pretty well," she said laughing, "I hate to ask, but would you change the bandsaw blade for me."

"No, but I'll help you do it whenever you want."

She cut herself slightly the last time she changed the blade herself, and she'd been frightened of it since then. Caitlin was very good at running most of the machinery, but she didn't trust the bandsaw anymore. I can't blame her, I don't trust the lathe personally.

Caitlin was about average height, maybe 5'-5" I'd never seen her wearing anything but our company coveralls, but I bet she was hiding a really nice figure. I'd definitely have to pursue her after I got over Kelly someday.

I helped her change the blade and she asked me about the massager so I offered to show her. I started on her arm.

"Wow! That feels really good actually," she said after shivering slightly, "you made this?"

"Yes I did, it was actually Mike's project that he gave up on." I said while moving the ring up her arm towards her shoulder, "I gave him a bunch of advice that he didn't take. I figured I'd see if my advice was any good." I moved it to the back of her neck. "What do you think?"

Caitlin didn't respond, her eyes looked unfocused. I guessed she was really enjoying the ring. I thought to myself that I might need to actually sell these things.

Caitlin's was very pretty I'd never noticed how big and deep green her eyes were, or how cute her nose was. Some girls had cute faces, some were sexy, and some were just plain. Caitlin had an adorable, almost innocent look to her, but with a hint of mischievousness... if that makes any sense. Honestly, it was probably just my slight obsession with redheads talking.

I absentmindedly moved the ring up her neck to just behind her ear. Her mouth parted just a little and she looked almost hypnotized. It was kind of a turn-on, but I tried to ignore it.

"Caitlin, I'm glad you asked me for help with the bandsaw today," I said nicely, "you should always feel comfortable with me helping you."

I was cringing for a minute at how I said that when she suddenly said in a slightly monotone voice "I always feel comfortable with you helping me."

Just then the battery died, her eyes regained focus, and I quickly moved my hand.

"That works really well Clayton, you should make more of these," Caitlin said as she hopped up out of my office chair. "And thanks for helping me with the bandsaw. I don't normally ask others for help, I'm very independent you know! But I think I'm actually comfortable with your help." With that, she turned and went back to the machine shop to clean up.

"That was weird," I thought to myself. First I dazed off when using it, then Caitlin did. And she parroted back what I said to her in monotone. Then after it died she immediately woke up like nothing happened.

"There's no way this actually hypnotizes people," I whispered to myself "I've got to test this out some more."

First I checked the timer on my phone. The battery died after about 35 minutes. Which is pretty impressive for that small of a device. Next, I checked the security camera footage from when I was using it before Caitlin woke me up.

"No way!" I said in disbelief. I sat completely still for 5 minutes with the ring on my neck before Caitlin woke me. I didn't remember more than 1 second of that time.

-Chapter 5-

I put the ring on the charging dock and confirmed it was charging. I also went ahead and made a massive bulk order of all the parts I used to make the ring. I had to see if this could be replicated. I put a couple more of my original design ring in the 3D printer print queue.

I opened up SolidWerks and made a 1/2 scale version to see if I could make it into an actually wearable ring. I added a small button to turn it on and off because it would have very limited battery life at that size. Maybe 5-10 minutes. I set a couple of these models to print as well.

It was closing time by the time I finished. With everyone gone I needed to test one more thing.

Did my suggestion that Caitlin ALWAYS feels comfortable with me helping her actually work? I'd read about post-hypnotic suggestions before, but assumed they were BS. Of course, I also considered this might be something more than hypnosis too. Hypnotism isn't instant, and a trance doesn't typically end instantly if the pendant so to speak, is taken away. This hypnotic state ended the second my ring turned off.

Caitlin and I both shut down all the equipment and closed together. Usually, we did our own thing so we could go home sooner. I kept dropping "let me help you..." and she never seemed bothered.

This had to be real. If I would have been breathing over her shoulder helping any other time. She would have and should have been pissed.

I finally got a chance to really test my helpfulness.

"I'm going to run to the restroom before we clean out the dust collectors," Caitlin said.

I cringed, but I asked, "would you like me to help you get out of those coveralls? I know it's a pain to get them off to use the restroom." I was waiting for a slap or an incredulous remark...

Caitlin replied, "sure if you want to help I'm comfortable with it, but it's not necessary..."

"Ok, I'll just help you right here if that's ok?" I asked and she stopped and nodded ok.

On the verge of hyperventilating, I grabbed the zipper at her neck and pulled it down. Underneath she was wearing a plain white tank top with clearly no bra. She had prominent nipples showing through on tits that were much larger than I expected. Probably Ds. The baggy coveralls hid them well. As the zipper reached her waistline I could tell she was very fit with her tight bare midriff.

I reached down and pulled off both of her shoes and held her steady as she stepped out of the coveralls. She was just wearing some plain athletic shorts, but she looked way better than I imagined. She had a nice ass, probably hard-earned in the gym, and long smooth legs.

"Can I help you take anything else off?" I asked as charming as I could muster, fully preparing to brush it off as a bad joke.

Caitlin smiled and said, "if I needed to take anything all the way off I'd let you help, but I don't need to." Then she turned and walked away.

Flabbergasted, I watched her walk a little longer than necessary before I went and sat down.

"It works!" I said a little louder than I anticipated. Luckily no one heard me.

"I can save my relationship with Kelly, with this... maybe."

-Chapter 6-

I figured I should take this slow and figure out more of how this worked trying on Kelly. Kelly would be a much harder egg to crack if any of this followed hypnosis rules. She definitely wouldn't be willing to change. She'd shown that to me pretty well over the years we spent together.

Caitlin was the obvious choice for testing. I had more opportunities to observe her and test on her throughout the day than I would anyone else. Plus, being the only full-time employees meant we spent a lot of time in private. The maker space rarely had customers in it during normal business hours. That's when we worked on improving the shop, maintenance, and occasional projects for local businesses.

It was two days later that I had a chance to do some more testing on Caitlin. The charging time for the device was too long to continue after we finished closing the first night, and she called in sick the next day. Luckily my bulk order of parts came overnight and was able to spend the day that she was gone building two new rings, and one of the smaller prototype wearable models. I also spent some time making a list of observations and questions for the device

1. It has a calming effect when used on (only tested arms so far)

2. It has a trancing effect when used on the neck or behind the ears (anywhere else?)

3. When in trance the subject is unaware of time passing or surroundings

4. When in trance the subject will respond to (some?) statements that will (or seem to be) followed after awakening

5. Behind the ear seems to be especially effective for trancing

6. The user can accidentally (or I guess intentionally) trance themselves.

7. The subject can be awakened by someone saying their name loudly (any other way?)

8. The subject doesn't remember being in a trance or the commands given to them.

Questions: long-term effects, stacking commands, do multiple rings increase trance, what happens if rings are used on erogenous zones... etc

Before we opened the shop I asked Caitlin, "do you want to see the final production version of the ring?"

She came over to my desk to look at them. "Oh wow, you polished them up and rounded all the edges nicely! You know it would be cool if you could make it small enough to be worn on the finger all the time."

"Yeah I thought the same thing," I replied, "I figure I'll sell them together as a set with the more powerful full size and a wearable model. I have a prototype wearable one charging now."

"Oh cool! Let me know when it's done. I'd love to test it out," she said.

"Actually I was wondering if you'd let me test these final versions of the full size on you?" I asked. "I could use some feedback on if one, or two at a time is better, or if two is too much."

"Sure! But I get to test my next invention on you. She said with a smirk. "Let me get these coveralls off so we can give it a test through something a little thinner than a quarter-inch!"

This time she was wearing just basic sweatpants and a long sleeve shirt. It was much colder outside today.

I got her to sit down on a bench we had in the office and started using one ring all around her back. I didn't notice her eyes glassing over from this. She did look to be enjoying the massage though.

"I'm surprised it still kind of tingles through the shirt," she said, "it's not as much as when it was on my neck last time, but it still feels nice."

I continued trying a few things on her back, she even lifted the back of her shirt up a little to see how strong the shocks were on the more sensitive lower back area. She said it felt good. No trance though.

I went back up to her neck and her eyes immediately unfocused, and her breathing got slower. I moved the ring around the back of her head, even her forehead which was extremely weird. She didn't show any signs of awareness at all. Finally, I moved it just behind her ear and she let out a quiet moan as her lips parted slightly.
